Abstract
The textures of cold rolled Ni and Ni-Fe alloy foils are determined by the X-ray transmission pole figure method.
Ni-Fe alloys from pure Ni to 28 Ni-Fe, which have a face centered cubic lattice at room temperature, show the Cu-type rolling texture, {110}⟨112⟩+{112}⟨111⟩. In pure Ni and 50 Ni-Fe, the {112}⟨111⟩ component is stronger than the {110}⟨112⟩ component. Stacking-fault probability in pure Ni and 50 Ni-Fe alloy may be smaller than that of 70 and 79 Ni-Fe alloys.
Most ternary alloys of 78 Ni-Fe- (Cu, Cr, Mo, V, Nb & Ti) also show the Cu-type rolling texture except Nb. The rolling texture of Nb-Ni-Fe alloy foils is close to the α-brass type texture, {110}⟨112⟩.
Mo-permalloy (4.5 Mo-79.6 Ni-Fe) behaves in a different manner: It has the Cu-type rolling texture in thicker foils of the order of 0.1 mm, but its texture changes to a texture closer to the α-brass type when heavily rolled to a several micron thickness.
